Anybody here tow using a Tundra 5.7 w/SR5 and Towing pkg.?

Thanks for the many replys to this topic. I will have to find a 2000 lb. lighter T.T. to pull to feel comfortable with payload using the Tundra 5.7L. I was unaware of all the numbers involved in deciding how much to tow. WOW, you guys know a LOT of stuff about T.T.s and trucks. I have never heard of 10 ply tires that were mentioned for rear of truck to prevent fishtailing, I thought that is what sway bars were for. I have a LOT to learn it seems.
